About Peak Current
When using DC motors or pumps…
When we receive inquiries about adapters or built-in power supplies, and ask customers about their intended use, they often plan to use them with devices that incorporate DC motors or pumps.
This has become a common topic in recent times.
Products that use DC motors or pumps are surprisingly frequently used in familiar areas, such as fan drive units in electric fans and air purifiers, sewing machines, and the paper feeding mechanisms of scanners and copiers.
When we identify that our customer's equipment uses DC motors or pumps, we ask, “Is peak current an issue?”
Peak current refers to the instantaneous excessive current that occurs when driving a DC motor.
If this is overlooked, the power supply may enter a protection mode unintentionally, stopping the operation of the equipment, or it may cause early failure of components in the power supply, ultimately leading to equipment malfunction. Such issues may arise.
Addressing peak current in the early stages is advisable. Therefore, for customers requiring adjustments, we request waveform data of the peak current.
For customers who find it difficult to provide waveform data, we request information on the peak current’s maximum value and the duration of the pulse.
Our power supply lineup includes open-frame switching power supplies such as the 240W UOHC3240 series and the UOHL3240 series that support double peak loads, and AC adapters from the PA series which support double peak loads for 1 to 10 seconds.
Based on these standard models, we propose measures tailored to customer requirements while considering the safety of the power supply.
If you are considering using a power supply for devices like DC motors or pumps, where peak current is a concern, please feel free to contact us.
